Technical Field

Background

The lithium ion battery slurry glue beater is generally used in the stirring process of the lithium ion battery binder. In the normal preparation process of the lithium ion battery slurry, a binder polyvinylidene fluoride (PVDF for short in english) in the lithium ion battery positive electrode slurry and a binder carboxymethylcellulose sodium (CMC for short in english) in the negative electrode material are mixed with a liquid material before use, are subjected to gluing, and are then respectively mixed with powder materials and stirred. In general, the binder is premixed for 2-4 hours before being mixed with the powder. The traditional processing method is to use a stirrer to beat glue, and after the glue solution is beaten, powder and other auxiliary materials are added to stir the battery slurry. Therefore, in order to solve the problem that the conventional process is time-consuming, a special glue applicator is usually used for applying glue.

In the glue making process of the traditional glue making machine, a glue stirring unit of the adopted glue making machine is internally provided with a high-speed dispersing paddle, and the high-speed dispersing paddle is responsible for dispersing and refining glue particles in stirring so as to enable the dispersed and refined adhesive particles to be dissolved more easily, thereby enabling the glue to form a glue solution. However, because the density of the powdery binder is lower than that of the solvent, the powdery particles are agglomerated after contacting the solvent, float above the liquid level of the solvent and cannot fully contact the solvent, and cannot reach the high-speed area of the high-speed dispersing paddle for refining and accelerating the dissolution, so that the particles and the agglomerates are slowly dissolved, which causes no small trouble to the whole rubber material preparation process. Therefore, in the slurry preparation process, the high-speed dispersion time of the whole barrel of slurry needs to be prolonged to solve the corresponding problems. This results in a significant reduction in the efficiency of the dispenser.
